MOTOR-'VEHICLE STEERING-GEAR.

Bpeoiiieation of Letten Patent.

Patented Apr. 20, 1915.

Application iiled November 27, 1914. Serial No. 874,226.

whic Figure 1 is a plan view of a steering ear embodying one form of my invention; ig. 2 a front elevation thereof; Fig. 3 a vertical transverse sectional view.

The object of this invention is to rovide the steering gear of a motor vehic e with means for insuring the operativeness of the wheel-shifting devices should the usual parts of the gear become inoperative, whereby all those accidents which occur by reason of derangement in the shifting rods, etc., are avoided, as more fully hereinafter set forth.

The wheels of the vehicle are journaled on the spindles of the usual steering knuckles a,

each of which is mounted on a vertical pivot as usual, the pivot being supported on the ends of the axle b. The usual rearwardly extending arm c is attached to each knuckle and the rear ends of these arms are conso nected by means of rods d to a suitable means for shifting the rods from the steering wheel. In the resent instance, I illustrate a shaft e whicii may be connected to the steerin post in any suitable manner and i which is provided with a de ending arm or J crank f provided with a s ot h in which works a pin q attached to the meeting ends of the rods ci'. I have shown these rods in the present instance as integral, but it will 4o be understood that they may be in separate I parts. The arms o are also connected together b a rod z' which is parallel with the axle, an I also connect the spindle knuckles by still another rod z arranged in front of the axle, this lattei rod being ivotally connected at its ends to forwar ly extending arms carried by the respective knuckles. It wili be observed that by rotating shaft e in the appropriate direction, the wheels may to steer the vehicle in the usual manner. The rearwardl extendin arms o, the rear rod i and one o the rods may be said to constitute the usual common form of steering means, and the remaining rod d to- 5 gether with the front rod z' and the arms y' may be said to be supplemental parts which, in combination with said usual members, constitute my invention. It will be observed that with my arrangement of parts it will be practically out of the question to put the steering gear out of commission by reason of derangement of any of the operating arts. The breaking of one of the rods d wil still leave the apparatus operative., and, even should one of the rods z also be broken, the knuckles could still be shifted as usual. Nor would the destruction of both the rods i put the ap aratus out of commission if the two rods dp remain intact. It will therefore be seen that in my apparatus I provide a steering mechanism which only under very remote conditions will become inoperative. It will be observed that my invention is not confined to the details of construction shown and described. Any suitable means ma be provided for laterally shifting the ro s d simultaneously.

It will be seen that a feature of my invention is arranging the pivots in each of the pairs of arms in alinement the line of one series of ivots being parallel with the line of the ot er pivots at the other side of the vehicle, whereby the rods and the arms will in all adjustments form a parallelogram.

Having thus described my invention, what I claim is:

In combination with an axle steering knuckles and wheels, each of said knuckles being provided with a forwardly-extending arm and also with a rearwardly-extending arm, a pair of rods arranged parallel with the axle and having their ends pivotally connected to the respective arms, one of these rods being arranged in front of the axle and the other 1n the rear thereof, additional rods pivotally connected to the rearwardl extendin arms at points to the rear o said paralle rods, these additional rods being parallel with the aforesaid rods, and means connected to these additional rods to shift them in unison endwisely in a direction transversely of the vehicle, for the purpose set forth.

In testimony whereof I hereunto aiiix my signature in the presence of two witnesses.
